1) You're a woman who sees a handsome guy at a party.  You go up to him and say, "I'm fantastic in bed."  That's direct marketing.
2) You're at a party with friends and see a handsome guy.  One of your friends goes up to him, and pointing at you, says, "She's fantastic in bed."  That's advertising.
3) You see a handsome guy at a party and ask for his phone number.  The next day you call and say, "Hi, I'm fantastic in bed."  That's telemarketing.
4) You see a guy at a party;  you straighten your dress, walk up to him, and pour him a drink.  You say, "May I?" and reach up to straighten his tie, brushing your breast lightly against his arm, and then say, "By the way, I'm fantastic in bed."  That's public relations.
5) You're at a party and see a handsome guy.  He walks up to you and says, "I hear you're fantastic in bed."  That's brand recognition.
6) You're at a party and see a handsome guy.  He fancies you, but you talk him into going home with your friend.  That's a sales rep.
7) Your friend can't satisfy him, so he calls you.  That's tech support.
8) You're on your way to a party when you realize that there could be handsome men in all those houses you're passing, so you climb to a rooftop and shout at the top of your lungs, "I'm fantastic in bed."  That's Facebook.
